Brief Introduction
Pentaerythritol, as a quaternary alcohol, is easy to be esterified to form acids and esters, so it is mostly used as raw material of alkyd resin coatings, mainly used as building coatings and automotive primer. Pentaerythritol tetranitrate can be obtained by esterification of pentaerythritol and concentrated nitric acid at 5 ~ 15 ℃ in industry. It is a kind of high-performance and strong explosive with higher explosive power than TNT. It is often used as booster or mixed with TNT. It was used extensively in the Second World War. It is a long-acting vasodilator and can treat angina pectoris. Pentaerythritol rosin ester can be prepared by the reaction of pentaerythritol and rosin acid. It can be mixed with dry oil to obtain a coating with good hardness, water resistance and weather resistance. It can be used for varnishes, floor inks, etc. An alkyd resin coating can be prepared by esterification polycondensation of pentaerythritol or glycerin with phthalic anhydride and fatty acid. The properties of alkyd resin can be improved by using different kinds and different amounts of fatty acids, making it suitable for various needs of coatings. It is widely used as metal, wood surface coating, for bridges, railways, derricks, housing construction and other commonly used industrial paint and architectural paint. Alkyd resin has developed rapidly since it entered industrial production in 1927 due to its low price, easy availability of raw materials, easy modification, strong adaptability and good comprehensiveness.

Brief Introduction
Tranexamic acid is a synthetic amino acid antifibrinolytic drug, which can competitively inhibit the combination of lysine and plasmin of fibrin, so as to inhibit the cracking of fibrin clot and produce hemostasis. It is mainly used in various bleeding caused by hyperfibrinolysis in clinic. Tranexamic acid is a synthetic lysine analogue, which can competitively bind to the lysine binding site on plasminogen and plasmin, so as to competitively inhibit the degradation of fibrin, reduce fibrinolytic activity and play a role in promoting coagulation. Theoretically, the use of tranexamic acid can lead to insufficient fibrinolytic activity, so it may increase the risk of postoperative thrombotic events.

Brief Introduction
Anastrozole is a potent selective three azole aromatase inhibitor, which inhibits the cytochrome P-450 dependent aromatase and thus blocks the biosynthesis of estrogen. Estrogen is a major factor in stimulating the growth of breast cancer cells. Letrozole is suitable for postmenopausal women with advanced breast cancer, and is used for second-line treatment after the failure of anti estrogen therapy.
